How to make
Divide up the sugar into 2 containers. Beat 1/2 of it with 5 egg whites and the other half with the 5 yolks, add the oil and beat again.
Combine the beaten yolks and whites and stir with a wooden utensil so the whites don't flatten.
Add the flour with baking powder and stir. Divide the mixture into 2, add the cocoa to 1 of them.
Pour into a form and bake at 360°F (180 °C) until ready.
